Force & Motion

Define motion

• a change in direction

• a change in temperature

• a change in position

• a change in size

How can motion be measured?

• by calculating the weight of an object

• by calculating the speed of an object

• by calculating the size of an object

• by calculating the length of an object

Which of the following does NOT show acceleration?

• speeding up

• slowing down

• turning right

• moving at same speed & direction

What is a force?

• weather

• how much matter is in an object

• a push or a pull

• how fast an object is moving

What is inertia?

• the tendency of an object to resist change to its state of motion

• the tendency of an object to stop moving

• the tendency of an object to start moving

• the tendency of an object to turn a corner

Define the term mass

• a push or a pull

• the speed of an object

• a force

• how much matter is in an object; measured by weight

How does mass effect inertia?

• less mass = greater inertia

• greater mass = greater inertia

• mass does not effect inertia

• greater mass = less inertia
